NlTED STAT-Es WILLIAM F. TROAST, OF .OONNELLSVILLE, PENNSYLVANIA, ASSIGNOR TO THE SLAYMAKER-BARRY COMPANY, OF SAME PLACE.

CYLINDER-LOCK.

SPECIFICATION forming part of Letters Patent No. 591,106, dated October 5, 1897. Application filed December 16, 1896. Serial No. 615,906. (No model.)

To all whom, iv may concern:

Be it known that 1, WILLIAM F. TROAST, a citizen of the United States, residingat Oonnellsville, in the county of Fayette, State of Pennsylvania, have invented certain Improvements in Night-Latches, of which the following is a specification.

This invention relates to improvements in night-latches, being more particularly applicable to cylinder pin-tumbler locks; and the objects of the invention are, first, to so construct the spindle as to overcome any divergence of the handle of the lock-case and the keyhole of the pin-tumbler from a line at right angles with the sides of the door; and, second, to simplify and cheapen the construction, whereby is secured in place the spindle-sleeve carrying the wings through which the bolt is actuated.

The invention consists in the construction and combination of the various parts, as hereinafter fully described, and then pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top edge view of a lock embodying my improvements, a part of the case being cut away and showing in section the portion of the door to which the lock is attached. Fig. 2 is a side view of the pin-cylinder and the spindle, a portion of the head of the key-hub being cut away; and Fig. 3 is an inner end view of the pin-cylinder and: the spindle. Fig. 4 is an inner face View of a portion of the back-plate in which the spindle-sleeve is secured, and Fig. 5 a vertical section on broken line 5 5 of Fig. 4..

Similar letters indicate like parts throughout the several views.

Referring to the details of the drawings, A indicates the door; B, the lock; 13, thebolt; B one of the stems of the bolt engaged by one of the wings on the spindle-sleeve; and B the revoluble handle on the inside of the lock, having a centrally-located longitudinal socket b therein.

D indicates the pin-cylinder, having on the sides thereof the ears d, through threaded openings in which pass the screw-bolts D, that secure the pin-cylinder in place.

D is the head of the pin-cylinder, which bears against the face of the door, and D is the escutcheon.

E is the head of the key hub or cylinder of by screws 6. Said head E laps and bears against the inner end of the pin-cylinder and secures the key-hub therein. Said pin-cylinder and key-hub form no part of this invention, but are of any well-known construction, and they are therefore not more specifically described.

In the center of head E is a rectangular opening 6, which is loosely engaged by an end f of the rectangular spindle F, as shown inFig. 2. On opposite sides of opening 6 and spindle F rectangular studs E E respectively, are formed with said head, and on the outer edge of the end face of said stud E is an inwardly-projecting rectangular and elongated shoulder e A thin rectangular plate G is secured to the end face of stud E by a single rivet g, the outer edge of said plate bearing against shoulder e This single rivet is enabled to hold the plate G in a rigid position because of the bearing of the outer edge of said plate against the elongated shoulder 6 The inner end of plate G projects beyond the edge of stud E and loosely engages a notch f in the side of spindle F, thus retaining end f of said spindle in engagement with opening 6 in head E. The space between studs E E is greater than the thickness of spindle F. Notch f is wider than the thickness of plateG and the depth of the notch is greater than the penetration of said plate, so that the connection between head E and the spindle forms a universal joint, allowing said spindle to play in its seat in any direction. This construction permits the spindle to be connected with the proper parts in the case under all practical conditions, for in securing a lock to a door there is generally a slight divergence between the normal line of the spindle and the openings in the case engaged thereby. This'divergence, though slight, is frequently just so muchas to pre vent the spindle from engaging the key-hub and the revoluble handle of the case, while there is sufficient play of said spindle in both of those parts to permit it to engage the handle after passing through the key-hub. The socket b in handle B extends to the end plate of said handle, thus permitting the adaptation of the lock to doors of different thicknesses, the free end f of the spindle ex- ICC tending about half-way through the handle broken lines F, Figs. 1 and 2, is exaggerated,

to fully illustrate the principle of action.

B indicates the back-plate of the lock-case and H the spindle-sleeve revoluble in an opening in said back-plate and having rigidly secured thereto the wings h, through which the stem or stems B of the bolt B are retracted.

Instead of riveting over the outer end of the spindle-sleeve to prevent inward displacement thereof, or of forming an angular flange on that end and riveting the wing-plate H thereto after said sleeve is engaged with the opening in the back-plate, I first attach the wing-plate to the spindle-sleeve, insert the spindle-sleeve in said opening, and then secure the same in place by means of a keeperplate M, illustrated in Figs. t and 5. This keeper-plate is secured as follows: On the back-plate, and in rear of the spindle-sleeve, is formed a supporting-block N, having on the center of its rear end a tongue 02 lengthwise thereof. The front end of the keeper-plate, having an orifice m, that registers with the spindle-opening h in the spindle-sleeve,bears on the inner end of said sleeve while the rear end of said plate rests upon block N, a notch in the plate engaging the tongue 7% on said block. On the forward part of block N is a stud n, that engages a corresponding opening in the keeper-plate. eted over to secure the plate in place, or it may have a soldered connection therewith, as

shown at m, Fig. 4. The engagement of tongue 12 with the notch in the keeper-plate 1 permits said plate to be rigidly held in place by but one stud, and the soldering allows 1 the connection between the back-plate and the keeper-plate to be readily severed, so that, when necessary, the spindle-sleeve can of said lock, wings on the sleeve, a block on easily be detached from said back-plate.

Spindle-sleeve H is operated to actuate bolt 13 either by a key through the key-hub or by the knob B I do not confine myself to the details of construction herein shown and described, as it is obvious that many alterations may be made therein Without departing from the principle and scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, in a night-latch, of a key-hub, a spindle having an end loosely seated in an opening in the end of said hub, a stud on the side of said opening, a plate on the stud and having the inner end loosely engaging a notch in the spindle, means for preventing the detachment of the spindle from said plate, and the revoluble parts of This stud may be rivj the lock, adapted to be engaged by the spindle, for the purpose specified.

2. The combination, in a night-latch, of a key-hub, a spindle having an end loosely seated in an opening in the end of said hub, studs on the end of the key-hub and on opposite sides of said opening therein, the space between the studs being greater than the thickness of the spindle, a plate on one of the studs and loosely engaging a notch in the spindle, the depth of said notch being greater than the normal penetration of said plate, and the revoluble parts of the lock, adapted to be engaged by said spindle, substantially as and for the purpose specified.

3. The combination, in a night-latch, of a key-hub, a spindle having an end loosely seated in an opening in the end of said hub, a stud on one side of said opening and having a shoulder on the outer edge thereof, a plate on said stud and bearing against said shoulder, the inner end of the plate loosely engaging a notch in the spindle, a single rivet securing the plate to the stud, means for preventing the detachment of the spindle from said plate, and the revoluble parts of the lock, adapted to be engaged by said spindle, for the purpose specified.

4. The combination, in a night-latch, of a key-hub, a spindle having an end loosely seated in an opening in the end of said hub, studs on the end of the key-hub and on opposite sides of said opening, the space between the studs being greater than the thickness of thespindle, a shoulder on one of said studs, a plate on the shouldered stud and hearing against said shoulder, said plate loosely engaging a notch in the spindle, the depth of said notch being greater than the normal penetration of said plate, a single rivet securing the plate to the stud, and the revoluble parts of the lock, adapted to be engaged by said spindle, for the purpose specified.

5. The combination, in a lock, of a revoluble sleeve located in an opening in a plate one side of said sleeve, and a plate secured on said block and bearing on the end of the sleeve to which said wings are attached, for the purpose specified.

6. The combination, in a lock, of a revoluble sleeve located in an opening in a plate of said lock, wings on the sleeve, a block on one side of said sleeve, a tongue on said block, a plate on the block and having a notch engaging said tongue, the plate bearing on the end of the sleeve to which said wings are attached, a single stud on the block and engaging an opening in the plate, and means adapting the stud to secure the plate in place, substantially as and for the purpose specified.
